    After rebuilding my carb it has started to cut out on steep uphill climbs. It doesnt feel like it's flooding but not sure. the engine starts to cut out until i give more throttle, but then the front end starts hopping and things get hairy. I was told by a guy on the trail to add an inline press regulator, and turn it down when I do steep climbs. Has anyone else had this prob? What did you do to solve it?

    Have you extended the vent lines? The float boals have vents that can splash fuel into the primaries (secondaries generally arn't open when going over ruff stuff). I added a 3" piece of fuel line to mine and it cured it.
     
  3. My rebuilt Q-Jet used to do that, then I advanced my timing a bit, and havent had it kill on me yet. Later 80K20

    Try setting your float a little lower and see if that helps.

    Set your float really low. I did that on my Jimmy and can climb almost vertical. The only problem with that is on the street it runs way lean and whan you floor it, it doesnt get enough gas and hesitates.
